Step One: Watch Mary Rose Cook Live Codes Space Invaders from Front-Trends. (The second worst conference name ever?)
Step Two: Fork this gist.
Step Three: Respond to this question in your fork: What is one approach you can take from this Mary's code and implement in your project?
Step Four: Totally Optional: take a look at some of the other forks and comment if the spirit moves you.
Honestly, when I first started reading about this project I had NO IDEA where to even start. So, being able to watch something completely from scratch is very very helpful. She is really helpful in deciding how code should be broken up into its modules and the functionality of 'this' as well. She also does a really good job of walking through OO with functions, modules, etc. I have also never seen anyone code a full app live with such confidence!
